Some of the best pizza I have eat my wife has made from scratch, and cooked on our grill. She makes a beer dough and tosses on some great toppings. Yummy.
I used to make bagel pizza's when I was younger. Take a bagel, open it up so you have two halves, toss on some tomato sauce some spicies and some cheese. Not as good as the wife's, but still pretty good. My dad makes a good pizza in the oven too.
